Foundations are completed for all the Oya Energy Hybrid Project's wind turbines.
POWERCHINA has completed the construction of all the foundations for 18 wind turbines of Oya Energy Hybrid Facility in South Africa. This milestone ushers in a critical phase of wind turbine installation, advancing the project toward grid connection and power generation.
As the world's largest integrated renewable energy facility under construction, the project combines wind, solar, and storage systems to harness energy from multiple sources.
It plans to install 18 wind turbines with the unit capacity of 4.8 MW. Positioned along a mountain ridge at altitudes of 1,100 to 1,400 meters, 6 turbines have already been erected.
The foundations are featured with an innovative design of anchor cage gravity expansion with a base diameter of 19.6 meters, a top diameter of 6.2 meters, and a total height of 3.8 meters. Each foundation integrates approximately 84 metric tons of steel reinforcement.
POWERCHINA has overcome significant natural challenges, including complex mountainous terrain and frequent severe weather. To date, 9,680 cubic meters of concrete have been poured, with all quality inspections meeting South African engineering and design standards.
Moving forward, POWERCHINA will prioritize foundation maintenance and site clearance while enhancing quality control. By adapting to onsite conditions, the team aims to ensure smooth wind turbine installation through a controlled, traceable, and verifiable construction process.
As a key national project for South Africa, it will provide a reliable and stable supply of clean energy to the national grid, supporting communities, cities, and the country in achieving a sustainable energy supply. This will help alleviate South Africa's periodic power outages and electricity shortages.
